I for one do not believe Romantiscm and Utopian are identical themes as Romance involves love, heroism and adventure while Utopias are perfect in function (thus making the concepts of love and heroism obosolete).
IMO Tomorrowland should retain the kinda already there romantic theme and give us our hero's and adventures rather than being a "perfect" society.
To me a Utopian theme would strive to be educational (which is Tomorrowland's original goal)...but it would be teaching something impossible. That's not cool with me. Romantic adventures would still appeal to all age groups and go well with the provided backdrop.
